Do you not see how the ships run upon the sea, by the Favor of Allah so that He may show you His signs? Surely, there are signs in this for every steadfast, thankful person. 31 When the waves, like shadows, envelop them, they call to Allah making their religion sincerely His, but no sooner does He bring them safely to land then some of them are halfhearted. None denies Our verses, except the ungrateful traitor. 32 Mankind! fear your Lord and dread a Day whereon no father shall atone for his son, and no son shall atone for his father at all. Verily the promise of Allah is true. Let not the life of the world beguile you, and let not the great beguiler beguile you in regard to Allah. 33 Only God has the knowledge of the Hour. He sends rain from the heavens, and knows what is in the mothers' wombs. No one knows what he will do on the morrow; no one knows in what land he will die. Surely God knows and is cognisant. 34
